Simon Cowell demanded 'X Factor' bosses got Dannii Minogue back on the judging panel of the talent show this year because he thought viewers would enjoying looking at her breasts

The music mogul wanted the 40-year-old singer - who reportedly had a secret relationship with Simon, which was revealed in May - to return as a judge on the ITV1 talent show so viewers could look at her breasts, and he is said to have urged producers to spend millions on a deal for the Australian star.

In an updated chapter of his biography 'Sweet Revenge, The Intimate Life of Simon Cowell', he told ITV Director of Television Peter Fincham earlier this year: "Bring her back to 'X Factor' ... everyone will be looking at her t**s."

His comments come after his affair with Dannii was revealed in the book - which is written by journalist Tom Bower - and he admitted to being obsessed with her "hair, the sexy clothes - and the t**s".

'X Factor' bosses were prepared to offer Dannii up to £2 million to get her on the panel for the current series as a replacement for last year's judge Kelly Rowland, but she was reportedly holding out for £5 million.

Nicole Scherzinger eventually joined the panel as the fourth permanent judge alongside Gary Barlow, Tulisa Contostavlos and Louis Walsh, but the show appears to be struggling after an average of 7.7 million viewers tuned in to Saturday night's (08.09.12) episode, down from the 11.1 million on the equivalent night last year.

But a source told The Sun newspaper: "We're confident ratings will rise."
